DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a new multifunctional abrasive belt fastening device for a polishing machine, comprising a base 1, a motor 2 is fixedly connected inside the base 1, a worm 3 is fixedly connected to the output end of the motor 2, a turntable 4 is rotatably connected inside the base 1, a worm wheel 5 is fixedly connected to the bottom of the turntable 4, the worm wheel 5 is meshed with the worm 3, a motor 2 7 is fixedly connected inside the turntable 4, a worm 2 6 is fixedly connected to the output end of the motor 27, a worm wheel 2 8 is rotatably connected inside the turntable 4, the worm wheel 2 8 is meshed with the worm 2 6, a transmission disk 9 is fixedly connected to the top of the worm wheel 2 8, a curved groove 10 is provided inside the transmission disk 9, a slider 11 is slidably connected inside the transmission disk 9, the outer wall of the slider 11 is slidably connected inside the curved groove 10, an active roller 12 and a driven roller 13 are rotatably connected to the top of the slider 11, a storage component is provided on one side of the outer wall of the base 1, and the storage component is used for storage function;

[0024] Specifically, when using the new multifunctional abrasive belt fastening device for a polishing machine, first start the motor 27, which serves as the power source of the entire transmission system. The rotation of the motor 27 drives the worm 26 to rotate, and the worm 26 meshes with the worm wheel 28 to convert the rotational motion into the rotation of the worm wheel 28. At this time, the transmission disk 9 will also be subjected to force and rotate accordingly. The rotation of the transmission disk 9 drives the slider 11 to move toward the center of the turntable 4. The movement of the slider 11 is achieved by the curved groove 10 on the transmission disk 9. This design ensures that the movement of the slider 11 is synchronized with the rotation of the transmission disk 9. The movement of the slider 11 will drive an active roller 12 The motor 12 and the two driven rollers 13 move so that the abrasive belt can be put on the active roller 12 and the driven roller 13. This process requires precise control to ensure that the tension of the abrasive belt is moderate to avoid being too tight or too loose, which affects the polishing effect. After the abrasive belt is put on, in order to ensure the fastening of the abrasive belt, the motor 2 7 will reverse, so that the slider 11 drives the active roller 12 to move in the opposite direction to further fasten the abrasive belt. The fastening process is achieved by adjusting the distance between the active roller 12 and the driven roller 13, so that the abrasive belt can maintain appropriate tension during the polishing process. When the polishing effect needs to be changed, the motor 2 can be started. The motor 2 drives the turntable 4 to rotate through the cooperation of the worm 3 and the worm wheel 5. The rotation of the turntable 4 will change the position of the abrasive belt, so that different parts of the abrasive belt contact the workpiece to achieve different polishing effects.

[0025] Reference Figure 1 - Figure 3 The storage assembly includes a tool box 14 and a handle 15, the bottom of the handle 15 is fixedly connected to the top of the tool box 14, and one side of the outer wall of the tool box 14 is fixedly connected to one side of the outer wall of the base 1;

[0026] Specifically, when using the novel multifunctional abrasive belt fastening device for a polishing machine, commonly used tools can be placed in the tool box 14, which helps to manage and maintain the tools, prevents the tools from being lost or damaged, and facilitates regular inspection and replenishment of the tools.

[0027] Reference Figure 1 - Figure 3 A motor 3 16 is fixedly connected inside the base 1, a screw 17 is fixedly connected to the output end of the motor 3 16, a slider 2 19 is threadedly connected to the outer wall of the screw 17, a slide groove 18 is opened inside the base 1, and the outer walls of the slider 2 19 are slidably connected inside the slide groove 18, a fixed block 20 is fixedly connected to the top of the slider 2 19, a cylinder 21 is fixedly connected inside the fixed block 20, a transmission block 22 is fixedly connected to the output end of the cylinder 21, and a transmission rod 23 is rotatably connected to the top of the transmission block 22, a slider 3 24 is slidably connected inside the fixed block 20, the top of the slider 3 24 is rotatably connected to the bottom of the transmission rod 23, and a clamping block 25 is fixedly connected to one side of the outer wall of the slider 3 24;

[0028] Specifically, when using the new multifunctional abrasive belt fastening device for a polishing machine, the operator first places the workpiece to be polished between the clamping blocks 25. The design of the clamping blocks 25 ensures that the workpiece can be stably fixed. Then the cylinder 21 is started. The contraction action of the cylinder 21 moves to the right through the transmission block 22. This action is achieved by pneumatic drive and has the characteristics of rapid response and precise control. The transmission block 22 pulls the transmission rod 23, and the transmission rod 23 then pulls the slider three 24 to form a coherent mechanical transmission chain. The movement of the slider three 24 drives the clamping block 25 to clamp the workpiece, ensuring that the workpiece remains stable during the polishing process to avoid uneven polishing or damage caused by the movement of the workpiece. After clamping the workpiece, the motor three 16 is started, and the motor three 16 drives the screw 17 to rotate. At this time, the slider two 19 is forced to move, and drives the fixed block 20 to move toward the abrasive belt until the workpiece to be polished contacts the abrasive belt. At this time, polishing work can be performed.

[0029] Working principle: When using the new multifunctional abrasive belt fastening device for the polishing machine, first start the motor 27, then the motor 27 drives the worm 26 to rotate, and then the worm 26 drives the worm wheel 28 to rotate. At this time, the rotation of the worm wheel 28 will drive the transmission disk 9 to rotate. When the transmission disk 9 rotates, the slider 11 will be forced to move toward the center of the turntable 4, and then the slider 11 drives the active roller 12 to move until the abrasive belt can be put on the active roller 12 and the driven roller 13. After the abrasive belt is put on, start the motor 27 to reverse, so that the slider 11 drives the active roller 12 to move in the opposite direction to tighten the abrasive belt. Then, place the workpiece to be polished between the clamping blocks 25, start the cylinder 21, and the cylinder 21 contracts to drive the transmission block 22 moves to the right, and then the transmission block 22 pulls the transmission rod 23, and at the same time the transmission rod 23 will also pull the slider three 24, so that the slider three 24 drives the clamping block 25 to move, and clamps the workpiece to be polished, then starts the active roller 12, so that the active roller 12 drives the abrasive belt to rotate, and then starts the motor three 16, the motor three 16 drives the screw rod 17 to rotate, so that the slider two 19 is forced to move to the upper left, and at the same time drives the fixed block 20 to move toward the abrasive belt until the workpiece to be polished contacts the abrasive belt. When it is necessary to switch the polishing effect, the motor one 2 can be started, and then the motor one 2 drives the worm wheel one 5 to rotate through the worm one 3, thereby driving the turntable 4 to rotate, changing the position of the abrasive belt, and using abrasive belts in different positions for polishing.
